Abstract
We are thrilled to share our collaboration with Zwerven met JuKi, a popular YouTube channel known for their practical and honest reviews of RV and off-grid gear. In their latest video, they put the Hoolike 12.8V 100Ah LiFePO₄ battery through a series of real-world tests, ranging from powering heavy appliances to disassembling the unit for a closer inspection. The result is one of the most thorough, hands-on demonstrations you can find online.

📦 First Impressions – Unboxing & Build Quality
The video begins with a quick look at the packaging (0:00–1:50). The hosts highlight the protective materials used, noting that the product arrives well-secured against shipping damage. Right after, they move into a general introduction of the battery (1:50–2:29), pointing out the key specifications and intended use cases—perfect for camping, RV life, and off-grid applications.
🔧 Setup & Initial Use
Once the box is opened, the hosts move on to mounting the battery (2:29–2:37) and preparing it for tests (2:38–3:20). Their first attempt is to run a heat blower (3:21–4:32), but the test is paused midway. Instead, they switch to monitoring the battery temperature while running a heater (4:33–5:05).
This step highlights an important safety feature: the battery actively regulates temperature to protect itself, preventing unsafe operation in extreme conditions.
🔥 Endurance with Heavy Appliances
The real test begins when they power up the heat blower again, running it continuously for almost two hours (5:06–6:20). During this, they use a DC clamp meter to measure amperage (5:46–5:55, 7:27–7:39).
Pushing the challenge further, they connect two heat blowers simultaneously (7:40–8:40). This intense load pushes the battery to its thermal protection limit, at which point the system automatically shuts down to prevent overheating. Far from being a weakness, this demonstrates the built-in safety mechanisms working exactly as designed—protecting both the user and the battery.
🛠️ Inside the Battery – Disassembly & Sensor Testing
After the stress tests, the team opens up the unit (8:41–12:45). Viewers get a rare look at the internal build quality: neatly arranged cells, a robust BMS (Battery Management System), and well-placed wiring.
They go even deeper, testing the internal temperature sensors under different conditions:
-
Charging while open (12:46–13:03)
-
Cooling the battery with ice (13:04–13:40)
-
Heating to trigger sensor shutdown (13:41–13:56)
Each test confirms that the BMS responds instantly, cutting power when unsafe temperatures are reached and reactivating once the system stabilizes. This is critical for long-term reliability, especially in the varied climates of Europe.
💧 Waterproofing & Safety
In the final segment (14:22–14:45), the hosts explain the waterproof design of the Hoolike battery. For RV owners and campers who often face rain, damp conditions, or unexpected splashes, this feature ensures dependable performance without risk of short circuits or damage.
🏕️ Final Thoughts
In their closing remarks (14:45–15:28), Zwerven met JuKi conclude that the Hoolike 12.8V 100Ah LiFePO₄ battery is more than just a power source. It’s a safe, durable, and versatile solution designed for real-world outdoor use. From powering high-demand appliances to surviving heat, cold, and water exposure, this battery is built to handle the unpredictable conditions of RV life and off-grid adventures.
